Indoor CSI (Channel State Information) fingerprint positioning method for rapid offline database establishment

The invention provides an indoor CSI fingerprint positioning method for rapid offline database establishment, and belongs to the technical field of indoor positioning. The method comprises the steps that CSI and position information of all positions of an indoor scene are collected in an off-line mode through a motion carrier, and a video image of the motion carrier is shot; the training target detection model is used for detecting a motion carrier in the video image; analyzing position information of a motion carrier by using the trained target detection model, combining target tracking with target detection, and introducing a weighted prior frame for target detection by using a target according to a result; time synchronization is carried out on the collected CSI and the position of a motion carrier, smoothing processing and sampling are carried out on a CSI sequence, CSI fingerprints are constructed and matched with position coordinates, an offline fingerprint map library is constructed, and online detecti
